SPECIFICATION forming part of Letters Patent No. 618,116, dated January 24, 1899.

Application filed .Tune l5, 1895. Serial No. 552,907. (No model.)

T0 all 1071/0771] it may concern:

Be it known that I, DON D. MILES, a citizen ofthe United States, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new-and useful Improvements in Magazine-Rides, of which the following is a specification.

Myinvention relates to magazine-guns, and has for its object to provide certainnew and useful features, such as are hereinafter described. I have desired particularly to so organize the various elements of the gun as to avoid in the greatest possible degree securing screws, bolts, and the like and so as to make easy work of assembling and disassembling the various parts. I have also desired to present means for the easy and certain eX- traction and ejection of the shell after the projectile has been discharged. I have also endeavored to produce certain improvements in the magazine-feed, to the end that the cartridges shall be presented in proper relation. I have also given particular attention to the organization of my gun in such manner that the user of the arm will be instantly advised when the magazine is empty and the gun will be retained in proper position for recharging the magazine. These several objects and others I have accomplished by the mech anisms and devices hereinafter described; but of course I am presentingin the drawings only one form of my invention, and I recognize at once that various changes can be made without materially departing from the spirit of my invention, and I do not wish, therefore, to be limited to the specific thing shown.

I will set out the characteristic method of action of the severalfeat-ures and desire to be protected in the use of such means as might be substituted for the means here illustrated to accomplish the same results in substantially the same way.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side view of the gun with the stock removed. Fig. 2 is a view of the other side of the gun with the stock in position. Fig. 3 is a vertical longitudinal section through the gun, showing the several parts with the stock removed. Fig. 4 is a similar section with some parts removed and showing the magazine empty and the last shell in process of being ejected. Fig. 5 is a side view of the breech-bolt and extractor in the relation which the parts assume when the bolt is ready to be withdrawn. View of the same with the bolt-lever shown in cross-section. Fig. 7 is a cross-section on the line 7 7 of Fig. 6,1ookingin the direction of the arrows. Fig. 8 is a rear end View taken on line 8 8 of Fig. 5 and lookingin the direction of the arrows. Fig. 9 is a view on the line 9 9 of Fig. 3, looking in the direction of the arrows and showing certain parts in front and behind such section in dotted lines. Fig. 10 is a similar view with the parts in a different position. Fig. llis a detail view ofthe extractor. Fig. 12 is a plan view of the magazine-feed and bottom plate. Fig. 13 is a plan View of the frame with certain parts,includingthe breechboit,removed. Fig. 14 is a section on line 14. 14, Fig. 8, with the magazine full of cartridges and shows the means of preventing the cartridges from being forced out of the magazine when the bolt is drawn back. Fig. l5 is a view of the arms or bars connected with the follower,which separates the cartridges in the magazine, the two arms being separated so as to show the manner in which they are connected together.

Like parts are indicated bythe same letter in all the figures.

A is the receiver, which is internally threaded at its forward end to receive the gun-barrel A', which contains the cartridge-chamber A2, the cartridges being indicated by ASA4 A5. Attached to and preferably continuous with the receiver is the rear portion B, which serves, as hereinafter described, as a support for various parts. The receiver is cut away, as indicated at Bl, to leave'a side slot or opening through which the cartridges can be inserted and the shells ejected. In the lower part of the forward end of the receiver is a recess B2, which recess is prolonged around the interior of the receiver until it opens out at the forward end of the aperture B'. On the upper inner side of the receiver there is also aslot B3, through which the extractor can be inserted. The receiver, has in addition a rear projection O, which is associated with the trigger-plate O', and these two parts are con- Fig. 6 is a plan' s sialic nected together and the stock C2 secured upon them by means of the transverse screw-bolt C3. The trigger-plate is provided with the loop C4 and the forward end C5, which is adapted to be slipped laterally into a recess or aperture in the lower portion of the part B.

CG is a thumb-piece on a locking-plate C7, one end of which is adapted to slide under the part C5 of the trigger-guard and hold it securely in position upon the part B. The trigger consists of the trigger proper, D, the central pivot portion D', and the upwardly-projecting part D2. The trigger-guard is shaped as indicated in Fig. 3, with the central aperture and the slots D3 D4 for the admission of the trigger. The stock, as indicated in Fig. 2, covers the trigger laterally, so as t0 retain it in its position.

The magazine is composed of the two end portions B and E, both of which are preferably continuous with the receiver, and the side portions El E2 and the bottom plate E3. The part E is recessed, as indicated, and provided with the aperture E4, through which projects the catch E5 on the bottom plate. This bot-- tom plate has the two side bearing-posts EG at its front end, which are hollowed out in opposition to a like arc-shaped place on the part E, so as to form a bearing for the pivotpiece F. The pivot-piece F consists of the enlarged portion F' and the smaller portion F2, both preferably made continuous with the bar F3, (see Fig. 15,) which bar is perforated at the other end to engage a projecting pin F4 on the follower F5.

F6 is a shorter arm provided with the part F7, which is received upon the smaller part F2 and which bears against the lower forward portion of the follower, as indicated.

F8 is a spring which is provided with a pin F9 to be received into a corresponding hole in the bottom of the magazine bottom plate and a pin F10 to be received into a hole in the upwardly-projecting rear portion of the bottorn plate. The forward end of the spring F8 bears against and upwardly forces the two bars F3 and F6, which bars are provided with cam-surfaces at the points where they are engaged by the spring, as indicated, so as to permit the two bars to rise responsive to the action of the spring and thus to carry the follower in such a manner as to make it accommodate itself to the number of cartridges in the magazine and present the uppermost cartridge at the proper position of parallelism with reference to the bolt, receiver, and barrel. This is accomplished by forming the cam-surfaces on the bars F3 and F6 at different angles, so that one of the bars will travel faster than the other. The rear end of the bottom piece is provided with an upward projection G, which is provided with a vertical semicircular slot at its rear end to receive the shaft G' on the locking-bar C7. This shaft has at its upper end a half-head G2, and the part B and the upward projection Gare both cut out to furnish room for such half-head. This half-head when in the position indicated in Fig. 3 will of course hold the parts together and the bottom in position, but when turned around to the opposite direction will be freed from the part B and will permit the bottom of the magazine, with its associated parts, to be removed.

J is an upwardly-projecting point or stop on the end of the bar F2, and thus associated with the follower, the oflice of which will be pointed out in connection with the other parts.

K ils the breech-bolt, hollowed outinteriorly at K K2 is the firing-pin, which passes through the small lock K3 and is provided with the centering-flange K4 and the striking-point K5. This point is adapted to project through the aperture K in the forward end of the breechbolt and thus to strike the head of the cartridge when the parts are in proper position.

The breech-bolt has at its forward end the locking-lug L, which is adapted to be received into the recess B2 and thus lock the bolt in position for tiring. It also has the lug L', with the forward-projecting portion L2, which is adapted to pass over on top of the lug L3 at the forward end of the extractor and thus hold the latter down in rigid relation to the bolt when desired. At the other end of the bolt is the enlarged portion M, from which .projects the lever M', preferably provided with the finger-ball M2 at its outer end. At the same end of the bolt and on the enlarged portion is formed the cam M3 by cutting out the metal of such enlarged portion at M4. This cam is adapted to engage the end M5 on the cooking-piece M6, so that when the bolt is rotated on its axis this cam will force the cooking-piece back, having reference to Fig. 3, thus compressing the spiral spring M7 within the bolt and about the firing-pin K2 and between the small lock K3 and the flange K4 until the parts are brought into the position indicated in Fig. 3. The parts are locked in this position by means of the sear N, which engages a shoulder on the cooking-piece, as indicated. The cooking-piece is provided with the thumb-piece M8, and the cookingpiece and firing-pin are secured together by means of the pivot pin M9, which passes through the cooking-piece and rotates therein, projecting into the channel for the firing-pin. The rotating pin is cut out at one side to receive the firing-pin and permit it to be inserted in such channel, and the firing-pin is cut ont at one side, so that when it is brought into. proper position the pivot-pin may be rotated so as to lock the firing-pin and cookingpiece together.

The sear is pivoted at N' to the elbow cranklever N2 and is upwardly forced by means of the spiral spring N3, which engages the lower side of the sear and rests upon the upper side of the step N4,proj ecting from the elbow cranklever. The sear is pivoted tothe elbow cranklever, as indicated in Fig. 3, its pivotal part being inserted sidewise into the recess in the elbow crank-lever therefor. The elbow cranklever has a somewhat similar portion N5, wherebyit is pivoted to the part B. One end of the elbow crank-lever N6 is interposed between the spiral spring N7, which bears against the part B and the part D2 of the trigger. The spring forces it outwardly and thus tends to keep the parts in the position indicated in Fig. 3. The other end of the elbow cranklever N8 bears upon the enlarged portion M of the breech-bolt, along the forward edge of such enlarged portionas, for example, at a point such as is indicated by N9; but when the gun is in condition to be discharged the bolt is situated so that the opening M4 is opposed to the end NS, and therefore the elbow crank-lever can be moved on its pivot to discharge the gun, though at other times it cannot be moved and the gun cannot be discharged.

In the forward portion of the part B there is a recess in which vertically reciprocates the ejector-pin O, provided with the flange O2 and surrounded by the spring O3, which bears against such liange and a shoulder in the recess and tends to force the ejector-pin upward. On the extreme upper end of the ejector-pin is secured the toe O4, which projects through a slot O5 in the forward end and on the lower side of the breechbolt K. This toe is adapted to engage the base of the shell O6 and eject it from the gun, as indicated in dotted lines in Fig. 4. When the parts are in this position and the lastcartridge and the last shell have been ejected, the follower F5 rises and permits the point J or causes the point J to rise to the position indicated and in the path of the bolt, so as to prevent forward motion of the bolt. Thus the gun cannot be closed or brought into position for firing until the magazine has again been charged and the operator has instant notice of the condition of his gun and the fact that the last cartridge has been discharged.

The slot O5 is cam-shaped, so that when the point J is out of the road the bolt can be moved forward and the ejector will be forced down into its position of preparation, as shown in Fig. 3. In the lower portion of the cocking-piece there is a recess P, into which the sear N is received when the gun is not cocked, so as to reduce the friction of the end N8 of the elbow crank-lever against the enlarged portion M of the breech-bolt during the rotation of such bolt. Furthermore, when the gun has been discharged the sear is permitted to rise into the recess P, so as to enable the spring N7 to easilyturn the elbow crank-lever on its pivot and retract the point N8 from the recess W1 and permit the bolt to be rotated on its axis.

The extractor consists of the springebar R, with the hook R', which is adapted to prodischarged and draw it slightly backward.

The other end of the extractor is provided with the dovetailed portion R2, with arcshaped ends R3 R3, and the concentrically-disposed pivot-pin R4. These parts are adapted to be received into corresponding recesses in the top of the small lock K3, and thus it is necessary for the extractor to be turned upon the pivot on the extractor-head before the two parts can be disengaged, and when in their normalpositions they are firmly attached together.

The extractor is provided with the inwardly projecting lug or leg R5, which engages when the parts are in proper position the forward edge of the bolt-head or enlarged portion of the bolt M, and thus locks t-he extractor-head to the bolt. This lug R5 is permitted to come into this position by the notch R on the forward end of the enlarged portion of the bolt. On the enlarged portion M, at the point indicated by Sin Figs. 5 and 6, is formed a cam, which cam is opposed to and engages the cam S', (indicated in dotted lines in Fig. 1,) so that when the bolt is rotated it is slightly retracted by the action of these two cams, and this takes place during the time when the extractor is locked down securely by the engagement of the lug L3 with the projecting part L2.

The device for locking the bolt and the firing-pin, so as to prevent the discharge of the gun, is indicated particularly in Figs. 5, 6, 7, and 8. On the side of the extractonhead is a projection T, which is bored out to receive the mutilated rod T, which rotates in such projection or sleeve T and is cut off at one side. Secured to and projecting from this rod is the arm T2, with the thumb-piece T3. On the arm T2 is the projecting portion T4. When the arm T2 is moved by the manipulation of the thumb-piece, which can only be done when the parts are in the position for firing, then the turning of the mutilated rod will cause it to engage 'a notch in the enlarged portion of the breech-bolt, which notch is indicated in Fig. 2 by dotted lines at T5, so that the bolt cannot be rotated. At the same time and by thesame action the projection T4 engages a slot or crosscut TG on the cockingpiece M6 and prevents the discharge of the gun.

, Two notches W W are provided in the receiver, asindicated in Fig. 13, to'permit ofthe easy introduction of the cartridges or the charger which contains them.

The cartridges when placed in the magazine are not placed in line, but are staggered, as shown in Fig. 14:. The top of the opening of the magazine near the bolt is contracted, as shown, the sides near the top end of the cartridge being curved, as shown at Z. When the bolt is in position, the top cartridge is prevented from being ejected from the receiver by means of said bolt. Vhen the bolt is drawn back, the top cartridge is moved up to the position shown in dotted lines in Fig. 14 and engages the curved surfaces Z, said cartridge being held in position by the cartridge below it, which tends to force it against said curved surface on account of the position of said cartridge-that is, on account of the fact that the cartridges are staggered.

The use and operation of my invention are probably sufciently set out in the foregoing description of parts and the drawings. vHowever, I will proceed to describe somewhat briefly the operation of the various parts.

Referring to the magazine, it will be observed that by the use of the single spring and the two pivoted bars which bear against the follower and are themselves borne against by the end of the spring the follower is forced up, its position conforming to that which is necessary for the proper feeding of the cartridges. rlhis action is further effected by the cam or curved surfaces of the spring and bars at their point of engagement. A lug on one of the bars, and of course it might be on the follower and in any event is'associated with the follower, projects up into the line of travel of the bolt. when the last cartridge has been used. By this means if the operator tries to push the bolt forward7 supposing that there is still a cartridge in the gun, he will nd the motion of the bolt intercepted at the start and will know by that at once that the magazine has been completely emptied, and he will obtain this information before the parts have gotten into an abnormal position and before the mouth or opening of the magazine has been closed, so that the instant that he feels the bolt checked in its forward motion he knows that the magazine is empty, and he will immediately proceed to fill it, whereupon and by which action the lug is taken out of the path of the bolt and the gun is free to operate.

In the matter of extracting the shell when the projectile has been discharged the operationis as follows: The hook on the end of the extractor passes into the slot at the forward end and in the upper interior portion of the receiver, and in this position the hook overhangs and tightly grasps the rim of the head of the cartridge. The cartridge having been discharged, it is necessary to extract the shell, and this sometimes requires considerable power. l have therefore provided the means illustrated. The lever M/ is moved upwardly, so as to rotate the bolt slightly, and two simultaneous actions ensue. The projection L2 on the lug L passes above or over the lug L3 on the extractor R, thus securely holding it down against the bolt and causing it to firmly hold the rim of the cartridge or shell; but at the same time and just as soon as the extractor has thus been clamped securely down the cam S on the enlarged portion of the bolt engages the corresponding cam S' 011 the inner surface of the receiver and moves the bolt slightly backward, thus loosening the cartridge or shell from its discharging-ohamber. The further -rotation of the lever and bolt to permit the withdrawing of the bolt carries the lug L2 beyond the lug L3 and frees the parts, the strength of the extractor R being sufficient from that time forward to hold the shell in position. The extractor is now brought toward the rear, the bolt having been brought into the position indicated in Fig. 5, and with the bolt and extractor comes the shell until the lower edge of its rim engages the toe O4, which toe has slipped into the slot O5, asindicated in Fig. 4. The sharp upward action of this toe'incident to the pressure of the spring O3 tips the shell, as indicated in dotted lines, and throws it out of the gu n. At the same time the spring in the bottom of the magazine moves the follower and cartridges up until the next cartridge is about opposite the end of the bolt, whereupon the forward motion of the bolt forces such cartridge int-o position for firing, as illustrated in Fig. 3.

Referring to Fig. 3, it will be seen that the firing-pin has been withdrawn, so as to compress the spring M7 by the action of the 'cocking-piece, the cooking-piece being held in retracted position by the scar N. Now if it is desired to lock the parts in this position it is accomplished by means of the thumb-piece T3 and pivoted arm T2, which when operated will cause the locking of the parts as follows: The mutilated bolt or rod T within the sleeve T engages the corresponding notch in the enlarged end of the bolt, so as to prevent rotation of the bolt, and at the same time the point or projection 'I4 on the arm T2 engages the corresponding slot TG in the cockingpiece and prevents it from being released, so as to permit the spring D 7to force the firingpin and cooking-piece forward. When these parts are moved up into the position indicated in Fig. S, all the parts are free to act, and lif the trigger be pulled the sear will be withdrawn, being forced down by the action of the elbow crank-lever against the action of the spring N2, whereupon the firing-pin is forced forward and the cartridge is discharged. This action or discharge can only take place when the parts are in the position indicated in Fig. l, at which time the notch or recess M4 in the enlarged end of the bolt is opposite the end N2 of the elbow cranklever, so that such elbow crank-lever can be moved to move the sear. Vhen the discharge has taken place, the sear rests in the recess IOO IOS

Ij on the cocking-piece and the parts will assume the position indicatedin Fig. 3, so as to permit the rotation of the bolt. The moment the bolt begins to rotate the end M5 of the cockingpiece engages the cam-surface M3, and the cocking-pieceis retracted until when the bolt has reached the limit of its rotation the cocking-piece has been restored to the position indicated in Fig. 3. The bolt is then retracted and the shell discharged. The

bolt is then forced forward, bringing the new cartridge into position for firing, andthe bolt is then turned so as to bring the parts into the position indicated in Fig l, where the gun is ready for discharging or where the parts may be locked in position by the manipulation of the thu nib-piece Tias above described.

It will be noticed that in putting this gun together no screws or the like are employed, with the exception of the single bolt which holds the stock and gun together. The sides of the magazine are undercut or dovetailed to the end pieces and are held in position by the bottom piece.

The method of inserting the trigger and the trigger-guard has been described; also, the method of inserting and pivoting the sear and the elbow crank-lever which controls it; also, the method of pivoting the two bars which control the follower; also, the method of locking the cocking-piece and firing-pin, and also the method of securing the extractor.

I have shown my gun in a concrete form, and the drawings are taken from a successfully-operative gun; but I have of course contemplated numerous alterations of greater or less importance and have also contemplated the use of a portion of these several devices with other devices. I do not therefore wish to be limited to the particular and precise forms here illustratedor to the complete combinations of all of these features. I wish the drawings and description to be taken as setting forth a particular form of my more general invention.

The cam-surfaces on bars F3 and F6 are necessarily at different angles, so that one of the bars will travel faster than the other. This is indicated by the varying position assumed by the bars in the drawings.

The cartridges when the bolt is drawn back are forced upwardly by the spring and bars and follower; but they engage the upper walls of the frame of the gun, so as to stop their upward motion.
